Automatically loads .idrsjson file in the plugins folder produced by ItemDisplayPlacementHelper export and applies it to a body specified inside it.
Replaces existing values in an ItemDisplayRuleSet. File order loading is undefined, so if multiple files add display for the same item/equipment whichever was loaded last will be the winner.
If skinName is not empty, R2API.Skins is used to add the rules only for that skin.
Any AssetBundle specified in the file must be loaded by the time catalogs are initialized.
If you want to manually pass json you can call IDRSJsonLoaderPlugin.ParseAndUpdate().
